MetroPCS has just announced a new unlimited talk, text, and LTE data plan, which is available for a limited time and costs just $55 per month for a single line. Families can pay just $50 for the account’s second, third, or fourth lines.

To make this offer really interesting, MetroPCS has also finally unveiled the LG Motion 4G smartphone, which we’ve first seen in July. This device will set you back just $149, and of course you can pair it with the aforementioned unlimited plan. It will be available online and in stores ‘later this week’.

The LG Motion 4G has a 3.5-inch 320×480 touchscreen, a dual-core 1.2 GHz processor, a 5 MP camera, 5 GB of built-in storage, microSD slot, a 1,700 mAh battery, and LTE connectivity of course. It runs Android 4.0 Ice Cream Sandwich, in fact being the first smartphone on MetroPCS to come with that software version.
